    Pleistocene hypothesis – moving Savanna perceptual preference hypothesis beyond Savanna

    We provide an extension of the Savanna perceptual preference hypothesis (“Savanna Hypothesis”), supposing that interaction with landscapes offering survival advantage for human groups during evolution might have gradually evolved to permanent landscape preferences. This additional support is based on the palaeoenvironmental analysis of the spread of modern humans into Europe in the late Pleistocene and their living environments there. Our hypothesis is that the preference for park-like landscapes after African savannas experienced a kind of “refreshment” in the Pleistocene. Thus, preferences for certain types of natural settings and scenes may have a more continuous evolutionary history than previously thought. The extended Savanna Hypothesis termed “Pleistocene Hypothesis” might stimulate further work on this important topic linking human evolution and human environmental preferences

    The relationship between perceived health and physical activity indoors, outdoors in built environments, and outdoors in nature

    BACKGROUND: A body of evidence shows that both physical activity and exposure to nature are connected to improved general and mental health. Experimental studies have consistently found short term positive effects of physical activity in nature compared with built environments. This study explores whether these benefits are also evident in everyday life, perceived over repeated contact with nature. The topic is important from the perspectives of city planning, individual well-being, and public health. METHODS: National survey data (n = 2,070) from Finland was analysed using structural regression analyses. Perceived general health, emotional well-being, and sleep quality were regressed on the weekly frequency of physical activity indoors, outdoors in built environments, and in nature. Socioeconomic factors and other plausible confounders were controlled for. RESULTS: Emotional well-being showed the most consistent positive connection to physical activity in nature, whereas general health was positively associated with physical activity in both built and natural outdoor settings. Better sleep quality was weakly connected to frequent physical activity in nature, but the connection was outweighed by other factors. CONCLUSION: The results indicate that nature provides an added value to the known benefits of physical activity. Repeated exercise in nature is, in particular, connected to better emotional well-being

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

    Memory and place attachment as predictors of imagined restorative perceptions of favourite places

    No full text
    Previous research linking favourite places and restorative environments hypothesises that place memory and place attachment can be implicated in restorative perceptions of place. In the present study, conducted with an online paradigm, 234 Finnish residents rated an imagined favourite place on place memory properties, place attachment, and imagined restorative perceptions. Autobiographical and positive affective properties of place memory were consistently predictive of perceived restorative potential of place. Attachment in the form of place identity and place dependence also positively predicted of restorative perceptions, and mediated certain relationships between memory properties and restorative perceptions. These findings highlight the relevance of top-down processing of restorative environments according to past experiences and individual attachments. This understudied topic may shed light on semantic values underpinning restoration in a range of settings, including favourite places

    Time- and Self-Related Memories Predict Restorative Perceptions of Favorite Places Via Place Identity

    Top–down processing has been highlighted as a potential, but as yet understudied, aspect of restorative environmental experience. In an online study, N = 234 adults resident in Finland rated their favorite Finnish place on measures of perceived restorativeness, perceived restorative outcomes, and place attachment, and provided qualitative descriptions of the place and a positive memory associated with it. Thematic analysis of qualitative data revealed seven themes underpinning place memories: the environment itself, activities within it, cognitive responses, emotional responses, social context, self, and time. Mediated regression analyses showed positive and significant relationships between restorative perceptions and the presence of memories of self and time, as mediated via place attachment (place identity factor). These findings emphasize the contribution of the person to the perception of their restorative experiences in places, particularly in the form of personal memories that can enhance place identity
